13 May 2019 --- Broccoli sprout-derived compound sulforaphane may help regulate a set of chemical imbalances in the brains of people with schizophrenia related to the chemical glutamate. This is according to researchers from the Johns Hopkins University School of Medicine (JHUSOM), US, who discovered how to tweak glutamate levels using sulforaphane. The researchers say that supplementation with broccoli sprout extract, which contains high levels of sulforaphane, could lower the doses of traditional antipsychotic medication, used to manage schizophrenia symptoms and reduce the negative side-effects of the drugs.
